When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.
This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.
Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.
Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.
The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

called after the __init time, so it must not call
any __init function, as the link-time warning reports.
Take away the __init annotation on proc_comm_boot_wait

Without this patch, building msm_defconfig results in:

On ARM some bits are specific to the model being emulated for the guest and
user space needs a way to tell the kernel about those bits. An example is mmio
device base addresses, where KVM must know the base address for a given device
to properly emulate mmio accesses within a certain address range or directly
map a device with virtualiation extensions into the guest address space.
We make this API ARM-specific as we haven't yet reached a consensus for a
generic API for all KVM architectures that will allow us to do something like
this.

If we want load epoch_cyc and epoch_ns atomically,
we should update epoch_cyc_copy first of all.
This notify reader that updating is in progress.
If we update epoch_cyc first like as current implementation,
there is subtle error case.
Look at the below example.
<Initial Condition>
cyc = 9
ns = 900
cyc_copy = 9
== CASE 1 ==
<CPU A = reader> <CPU B = updater>
write cyc = 10
read cyc = 10
read ns = 900
write ns = 1000
write cyc_copy = 10
read cyc_copy = 10
output = (10, 900)
== CASE 2 ==
<CPU A = reader> <CPU B = updater>
read cyc = 9
write cyc = 10
write ns = 1000
read ns = 1000
read cyc_copy = 9
write cyc_copy = 10
output = (9, 1000)
If atomic read is ensured, output should be (9, 900) or (10, 1000).
But, output in example case are not.
So, change updating sequence in order to correct this problem.

Any devices wishing to use the AB8500's GPIO IRQs were forced to

responsibility has been passed back to the AB8500 core driver,
devices can request real IRQ numbers instead. This patch removes
any traces of the old virtual IRQ conversion handlers, which will

AB8500 GPIO no longer handles its GPIO IRQs. Instead, the AB8500
core driver has taken back the responsibility. Prior to this
happening, the AB8500 GPIO driver provided a set of virtual IRQs
which were used as a pass-through. These virtual IRQs had a base
of MOP500_AB8500_VIR_GPIO_IRQ_BASE, which was passed though pdata.
We don't need to do this anymore, so we're pulling out the

Pull ARM fixes from Russell King:
"I was going to hold these off until v3.8 was out, and send them with a
stable tag, but as everyone else is pushing much bigger fixes which
Linus is accepting, let's save people from the hastle of having to
patch v3.8 back into working or use a stable kernel.
Looking at the diffstat, this really is high value for its size; this
is miniscule compared to how the -rc6 to tip diffstat currently looks.
So, four patches in this set:
- Punit Agrawal reports that the kernel no longer boots on MPCore due
to a new assumption made in the GIC code which isn't true of
earlier GIC designs. This is the biggest change in this set.
- Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
the DT-ification of the GIC support without fixing up non-DT
Realview - which now sees a greater number of interrupts than it
did before.
- A fix for the DMA coherent code from Marek which uses the wrong
check for atomic allocations; this can result in spinlock lockups
or other nasty effects.
- A fix from Will, which will affect all Android based platforms if
not applied (which use the 2G:2G VM split) - this causes
particularly 'make' to misbehave unless this bug is fixed."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned
ARM: DMA mapping: fix bad atomic test
ARM: realview: ensure that we have sufficient IRQs available
ARM: GIC: fix GIC cpumask initialization

We have received multiple reports of mmap failures when running with a
2:2 vm split. These manifest as either -EINVAL with a non page-aligned
address (ending 0xaaa) or a SEGV, depending on the application. The
issue is commonly observed in children of make, which appears to use
bottom-up mmap (assumedly because it changes the stack rlimit).
Further investigation reveals that this regression was triggered by
394ef6403a ("mm: use vm_unmapped_area() on arm architecture"), whereby
TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing
get_unmapped_area to choke on misaligned addressed.
This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of
TASK_SIZE and explicitly aligns the result to 16M, matching the other
end of the heap.

This happens because the DMA allocation code is not respecting atomic
allocations correctly.
GFP flags should not be tested for GFP_ATOMIC to determine if an
atomic allocation is being requested. GFP_ATOMIC is not a flag but
a value. The GFP bitmask flags are all prefixed with __GFP_.
The rest of the kernel tests for __GFP_WAIT not being set to indicate
an atomic allocation. We need to do the same.

Some early GIC implementations return zero for the first distributor
CPU routing register. This means we can't rely on that telling us
which CPU interface we're connected to. We know that these platforms
implement PPIs for IRQs 29-31 - but we shouldn't assume that these
will always be populated.
So, instead, scan for a non-zero CPU routing register in the first
32 IRQs and use that as our CPU mask.

The platform data is used not only by wlcore-based drivers, but also
by wl1251. Move it up in the directory hierarchy to reflect this.
Additionally, make it truly optional. At the moment, disabling
platform data while wl1251_sdio or wlcore_sdio are enabled doesn't
work, but it will be necessary when device tree support is
implemented.

This is w.r.t the changes in PHY library to support adding and getting
multiple PHYs of the same type. In the new design, the
binding information between the PHY and the USB controller should be
specified in the platform specific initialization code. So it's been
done here for OMAP platforms.

The PCI IRQs were regressing due to two things:
- The PCI glue layer was using an hard-coded IRQ 27 offset.
This caused the immediate regression.
- The SIC IRQ mask was inverted (i.e. a bit was indeed set to
one for each valid IRQ on the SIC, but accidentally inverted
in the init call). This has been around forever, but we have
been saved by some other forgiving code that would reserve
IRQ descriptors in this range, as the versatile is
non-sparse.
When the IRQs were bumped up 32 steps so as to avoid using IRQ
zero and avoid touching the 16 legacy IRQs, things broke.
Introduce an explicit valid mask for the IRQs that are active
on the PIC/SIC, and pass that. Use the BIT() macro from
<linux/bitops.h> to make sure we hit the right bits, readily
defined in <mach/platform.h>.

This pull request adds initial support for the Tegra114 SoC, which
integrates a quad-core ARM Cortex-A15 CPU. I'm proud to observe that we
posted the initial versions of these patches before the final official
announcement of this chip.
These patches are enough to boot with a UART-based console, support the
Dalmore and Pluto reference/evaluation boards, instantiate the GPIO and
pinctrl drivers, and enable a cpuidle state. As yet, no clocks or
storage devices are supported, but patches for those will follow shortly.
This pull request is based on (most of) the previous pull request with
tag tegra-for-3.9-soc-cpuidle, followed by a merge of the previous pull
request with tag tegra-for-3.9-scu-base-rework.

The Tegra USB driver has a number of issues:
1) The PHY driver isn't a true platform device, and doesn't implement
the standard USB PHY API.
2) struct device instance numbers were used to make decisions in the
driver, rather than being parameterized by DT or platform data.
This pull request solves issue (2), and lays the groundwork for solving
issue (1). The work on issue (1) involved introducing new DT nodes for
the USB PHYs, which in turn interacted with the Tegra common clock
framework changes, due to the move of clock lookups into device tree.
Hence, these USB driver changes are taken through the Tegra tree with
acks from USB maintainers.

Tegra already supports the common clock framework, but had issues:

drivers/clk/.
2) A single "Tegra clock" type was implemented, rather than separate
clock types for PLL, mux, divider, ... type in HW.
3) Clock lookups by device drivers were still driven by device name
and connection ID, rather than through device tree.
This pull request solves all three issues. This required some DT changes
to add clocks properties, and driver changes to request clocks more
"correctly". Finally, this rework allows all AUXDATA to be removed from
Tegra board files, and various duplicate clock lookup entries to be
removed from the driver.

Newer Exynos4 SoC are equipped with a local camera ISP that
controls external raw image sensor directly. Such sensors
can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to
the ISP, which then feeds image data to the FIMCn IP. Thus
there can be two busses associated with an image source
(sensor). Rename struct s5p_fimc_isp_info describing external
image sensor (video decoder) to struct fimc_source_info to
avoid confusion. bus_type is split into fimc_bus_type and
sensor_bus_type. The bus type enumeration is extended to
include both FIMC Writeback input types.
The bus_type enumeration and the data structure name in the
board files are modified according to the above changes.

Fix the use of USART on both at91sam9x5 and at91sam9n12. In DTS, the
atmel,use-dma-[rx|tx] property is present but a DMA channel cannot be used.
Indeed the connexion between the DMA engine and the slave is not implemented
yet in Device Tree.
Note however that this property is also used for PDC (private DMA) on older
SoCs. This is why the driver alone cannot determine the validity of this
property.

The mxc-timer on the imx25 needs to be derived from the AHB clock.
If a bootloader reparents this clock to the ipg_clk_highfreq, which according
to the datasheet is a valid operation, the system can/will produce lockups/
freezes after some time [1].
This can be forced with code like
while(1)
syscall(SYS_clock_gettime, CLOCK_REALTIME, &tp);
This was already fixed with the commit
"i.MX25 GPT clock fix: ensure correct the clock source" [2],
for 3.1-rc2, but was lost, when i.MX was converted to the common clock framework
("ARM i.MX25: implement clocks using common clock framework") [3]

Extend imx6q DEBUG_LL uart port selection support to cover all i.MX
SoCs. The 'range' of the Kconfig option gets dropped, as users
looking at the option must know the uart number on his board. The
bottom line is that the build system will report an error if an
invalid port number is picked for given SoC.
The header arch/arm/include/debug/imx-uart.h is created to accommodate
all the uart base addresses. And the header will also be used for
other low-level debug facility later.

It's improper to use combined symbol DEBUG_IMX31_IMX35_UART for

So later when we add UART port selection for DEBUG_IMX31_IMX35_UART,
we will have problem.
Use separated Kconfig options for imx31 and imx35 debug uart selection.
